According to an overview of the E-Reading Rises as Device Ownership Jumps report  from Pew Internet on January 16th…

The proportion of Americans who read e-books is growing, but few have completely replaced print books for electronic versions.

The percentage of adults who read an e-book in the past year has risen to 28%, up from 23% at the end of 2012. At the same time, about seven in ten Americans reported reading a book in print, up four percentage points after a slight dip in 2012, and 14% of adults listened to an audiobook.

Though e-books are rising in popularity, print remains the foundation of Americans’ reading habits. Most people who read e-books also read print books, and just 4% of readers are “e-book only.” Audiobook listeners have the most diverse reading habits overall, while fewer print readers consume books in other formats.
